lNSULATtOFt-SUFPOR'IT'n SPECIFICATION forming part of Letters Patent No. 783,230, dated February 21, 1905.

Application filed May 11, 1903. Serial No. 156,520.

To all who? it may concern..-

Be it known that I, LoUIs Srrnnnnnenn, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Insulator- Support, of which thefollowing is a full, clear, and exact description.

My invention relates to insulator-supports and admits of general use, but is more particularly adapted for use with a type of insulator employed for supporting outdoor wires which are exposed to the action of the weather.

The several purposes of my invention are stated in the following specification and pointed out in the appended claims.

I Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figurel is a front elevation of across-beam upon which my insulator-support is mounted, the insulator-support being partly shown in section; and Fig. 2 is a fragmentary central section through the lower part of the insulator-support.

A cross-beam is shown at 1. Mounted upon this cross-beam is a metallic stem 2, provided with a shoulder 23 and with a threaded portion at. Mounted upon the threaded portion 4 is a revoluble nut 5, which is locked in position by means of a second nut 6. The metallic stem 2 is provided with a reduced portion 7, having a thread 8. Revolubly mounted upon the threaded portion just mentioned is a threaded metallic sleeve 9, provided with a depending skirt 10, having a peripheral flange 11 of the shape indicated. The sleeve 9, the skirt 10, and the flange 11 are of course integral with each other and constitute a hollow metallic member having a general frusto-conical shape, as indicated in Fig. 1, and are used for the purpose of strengthening an envelop 12, mounted upon said hollow member. The envelop 12 is of insulating material and has the general form of a cone-frustum and is provided with threads 13 and with a w rathershield 14: of the shape indicated. An endless recess 15 completely encircles the insulation and at 16 is disposed comparatively near the l l them to flow off easily in a lateral direction.

\ any preferred form.

l l l cross-beam 1. The purpose of this recess is 'to guide falling elements such as rain, snow, dust, &c. downwardly to the conniaratively low point 16, thus leading them away from the vital parts of the mechanism and enabling so that the channel will lead the flow of water beyond the sides of the cross-arm, thereby preserving the pins from moisture and reducing the chances for arcing of the current. The threads 13 are provided for the purpose of supporting the insulator, which may be of "hen the device is mounted as indicated in Fig. 1, any rain, snow, or sleet which may fall within the recess 15 is guided off and escapes at 167 The cross-beam 1 is thus protected from the action of the water, sleet, &c.

1 do not limit myself to the particular form of stem shown. Neither am I limited to the particular arrangement of the insulating member relatively to the cross-arm nor to the exact form of the skirt as shown. It is obvious that persons skilled in the art may without departing from the spirit of my invention construct the parts mentioned in many other forms.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. An insulator-support, comprising a stem provided with a threaded portion, a metallic sleeve disposed concentric to said stem and provided with a threaded portion engaging said threaded portion of said stem and also with a skirt, and an insulating member mounted upon said metallic sleeve and engaging said skirt, said insulating member being provided \vitha portion for supporting an insulator.

2. An insulator-support, comprising a stem provided with a thread, a metallic vsleeve mounted upon said stem and provided with a thread engaging said thread thereof, said sleeve being further provided with a skirt, and a member of insulatingmaterial encircling said sleeve and provided with a spent for directing the flow of moisture. 3. An insulator-support, comprising a stem l provided with a threaded portion, a metallic l sleeve provided with a threaded portion en- 1 gaging said threaded portion of said stem and also provided with askirt, said skirt depending from said stem, and a member of insulat ing material encirclii'ig said sleeve and extending below the lower extremity thereof, said member of insulating material being provided with a spout.

p insulator-support, comprising a stem provided with a thread, a metallic sleeve mounted upon said stem and provided with a thread engaging said thread thereof, said sleeve being further provided with a skirt, and a member connected exteriorly with said sleeve and provided at its lower end with a gutter for directing the flow of moisture.

5. An insulator-support, comprising a stem provided with a threaded portion, a metallic sleeve provided with a threaded portion engaging said threaded portion of said stem and also provided with a skirt, said skirt depending from said stem, and a member connected exteriorly with said sleeve and extending below the lower extremity thereof, said member being provided with a portion for directing the flow of moisture.

6. An insulator-support,com prising a stem, a metallic member mounted thereon, and a member of insulating material mounted upon said metallic member, said member of insulating material beingclosed at its upper end and provided at its lower end with a spout and with portions raised higher than said spout for the purpose of directing the flow of moisture thereinto.

7. An insulator-support, comprising a stem provided with a thread, a metallic sleeve closed at one end and provided with a thread mating said thread of said stem, and a hollow member mounted upon said metallic member said hollow member having a portion formed into a spout and also having a portion raised relatively to the level of said spout for the pur- 3 pose of directing moisture thereinto,said members also having a closed upper end encircling the upper end of said stem.

8. As an article of manufacture, an insulator-support comprising a hollow member of in sulating material provided at its base with a water-shedding course, said course having raised side walls for directing the flow of water, and a hollow strengthening member engaging said member of insulating material and provided with a threaded portion for engaging a si'ipporting-pin.

9. An insulator-support, con'iprising a ho]- low member of insulating material provided at its base with a water-shedding course, said course having side walls elevated above said base for directing the How of water, and a ho]- low metallic member for strengthening said hollow member of insulating material.

10. An insulator-support, comprising a hollow member of insulating material provided with a base, and with side walls integral therewith and raised above the normal surface thereof for directing the flow of water, said member of insulating material being further provided with a hollow metallic membersecured imi'novable thereto for strei'igthei'ling the same.

11. In an insulator-support, the combination of a hollow member of insulating material provided at its base with a surface having walls raised relatively thereto for directing the flow of water, a hollow metalliclining for said hollow member, and mechanism connected with said hollow metallic lining for detachably mounting the same. 7

An insulator-support, comprising a member of insulating material provided at its base with a water-shedding course, said course having side walls elevated above said base for directing the flow of water, and a metallic support for strengthening said member of insulating material.

13. in an insulator-support, the combination of a member of insulating material provided with a base, and with side walls integral with said base and raised above the normal surface thereof for directing the llow of water, and a metallic member for strengtheuing and mounting the said member ofinsulating .material.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
